I'll try to take some today. It's actually gotten worse. All leaves are gone and now instead of mites I see little black bugs and what I'm guessing are their babies (they're bright red) on the stems. I just keep spraying the stems now with soapy water. It seems to get them, and I just cleared away the leaves that had dropped into the pot and covered the soil, and sprayed around the base, where it seems they were most concentrated.
They don't look like mites. I'll try to get pictures.
